Abstract:
Simultaneous comparison of planktivore and crustacean zooplankton distribution patterns in a set of British Columbia lakes suggested coupled diel vertical migration behavior in the two adjacent trophic levels. In lakes where juvenile sockeye salmon performed diel vertical migrations, most zooplankton were non-migratory and concentrated in shallow surface waters over the diel cycle. In contrast, in one lake where pelagic threespine sticklebacks were present, and where juvenile sockeye diel vertical migrations were periodically reversed, most zooplankton undertook diel vertical migrations. The presence of diel vertical migration behavior in zooplankton thus appears to be related to the presence or absence of the behavior in the predominant planktivores.

Abstract:
We conducted a multi-year acoustic telemetry study of lake trout (Salvelinus namaycush (Walbaum, 1792)) in a small subarctic lake to investigate depth and temperature occupancy, and vertical activity across seasons (summer, fall, and winter), diel periods (day, twilight, and night), and during summer periods of 24 h light (day and twilight). Analyses using generalized additive mixed models revealed a high degree of individual variation in depth occupancy independent of the factors hour of day, season, and diel period, whereas temperature occupancy and vertical activity were explained using the three combined factors. Habitats occupied were typically 9–20 m and 6–9.5 °C in summer, 1–3 m and 2–15 °C in fall during presumed spawning, and ≤6 m and <3 °C in winter. Lake trout exhibited partial diel migration where individuals displayed a variety of vertical migratory directions within and among seasons or diel period, including during periods of 24 h light. Fish were most vertically active during periods of daylight and in fall. During 24 h light, some lake trout performed crepuscular movements, whereas individual behaviour best explained modelled depth and temperature occupancy and vertical activity. The variety of vertical patterns among individuals and seasons suggests multifactor proximate causes of partial diel migration and crepuscular movements.

Abstract:
We used a bioenergetics-based foraging model to determine if bioenergetic and foraging constraints could explain kokanee (Oncorhynchus nerka) diel vertical migration in Blue Mesa Reservoir, Colorado. We compared model predictions of daily growth and migration strategies with observed growth and diel vertical distributions on three dates during the summer. Results suggest that bioenergetic and foraging constraints were not sufficient to explain diel vertical migration early in the summer, when thermal stratification was weak. However, these constraints could explain observed patterns later in the summer, when optimal thermal habitat for kokanee was spatially segregated from food-rich surface waters. The onset of a strong thermocline, and its exclusion of piscivorous lake trout (Salvelinus namaycush) from surface waters, appeared to determine the relative importance of predation risk for kokanee diel vertical migration patterns. Our observations and modeling results suggest that the relative importance of various factors driving diel vertical migration changes seasonally. Furthermore, the relative importance of each factor likely varies from system to system and may have caused the variety of single-factor hypotheses proposed to explain kokanee diel vertical migration. The model provides a framework for studying diel vertical migration across systems of differing thermal regimes, productivity, and predation pressures.

Abstract:
Dual-beam acoustic surveys of Okanagan Lake suggested active diel vertical migrations of Mysis relicta and kokanee (Oncorhynchus nerka) within the pelagic zone. Mysis relicta were situated between 90–150 m during the day and migrated upwards into the thermocline region of the water column at night. Two groups of kokanee targets were detected. The first undertook a diel vertical migration and coalesced at dusk with a second, shallow-oriented group of targets. Daytime target strength estimates taken while the two groups were vertically segregated in the water column suggested an 8–12 db lower target strength of the deeper group. The results provide acoustic evidence for a smaller body size in the deeper group and the occurrence of an ontogenetic shift in diel migratory behavior of kokanee within Okanagan Lake. Diel comparisons of depth distribution suggested spatial segregation of Mysis and kokanee over much of the diel cycle.

Abstract:
Mass animal migrations represent large movements of biomass, energy, and nutrients with predictable patterns and important ecosystem-level consequences. Diel vertical migration (DVM) in aquatic systems, the daily movement of organisms from deeper depths during the day to shallower depths in the water column at night, is widespread in freshwater and marine systems. Recent studies, however, suggest partial migration behavior, whereby only some portion of a population migrates, is the rule rather than the exception in a range of migratory fauna, including those that undergo DVM. Hypotheses to explain why partial migrations occur complicate traditional views on DVM and challenge conventional theories. I address intraspecific variation in DVM behavior of an aquatic omnivore, Mysis diluviana, to test several long-standing assumptions about benthic-pelagic DVM in Mysis. I evaluated the extent of partial DVM and several potential drivers within a Lake Champlain Mysis population. I used traditional net-based field observations, a novel deep-water video camera system, and a laboratory experiment, to compare distributions, demographics, abundance estimates, hunger-satiation state, and feeding behavior, of migrant and non-migrant Mysis across multiple seasons, habitats, and different times of the day. Findings from my dissertation suggest Mysis partial DVM is common, and is associated with body size and demographic differences among individuals. Partial DVM behavior, however, did not correspond to strong differences in feeding preference or hunger-satiation state of individuals. My results contribute toward a more comprehensive understanding of migration theory and mysid biology, by including the often overlooked, but important, benthic habitat component of DVM studies, and fills in several ecological knowledge gaps regarding a key omnivore in many deep lake food webs across North America where Mysis serve as both predators and prey to many organisms.

Abstract:
The diel vertical migration (DVM) of zooplankton has been extensively studied and reviewed. Yet the controlling mechanisms for DVIVI are still uncertain, although several hypotheses, e. g. predator evasion, hunger - satiation, light avoidance, have been proposed. This is particularly so for krill. An important part of understanding krill DVM depends on explaining the factors which drive krill to the surface waters at night. It is frequently speculated that krill migrate to the surface layers to feed. Although there is a vast literature on krill feeding (and the pattern of krill DVM) there has been little attempt to establish the role of feeding in DVIVI. Consequently, the main aims of this thesis were to further explore the mechanisms for krill DVIVI and also to explain the feeding strategy of krill in order to understand the role of feeding in DVM, using Northern krill Meganyctiphanes norvegica as a model system. These aims were achieved by examining the following: whether krill are selective feeders and also whether the morphology of the feeding basket constrains the food types that can be handled by krill; whether krill feed throughout DVM; the relationship between krill metabolism and feeding during DVM. Krill showed significantly greater feeding rates with larger food types compared with smaller food types and this size selection appeared to be at least in part related to the morphology of the feeding basket. Above all it seemed that krill were opportunistic omnivores and the food types handled by krill were affected by the morphology of the feeding basket. Krill also showed significantly greater feeding rates when' offered food types available during the night compared with during the day. Gut contents from field caught individuals supported that krill did not feed extensively during the day as day caught individuals had significantly less stomach pigment content compared with night caught individuals. As krill appeared to not feed extensively on day time available food types it raised the question 'is there a cost to not feeding extensively during the day'. There did appear to be a cost to the lower daytime feeding than compared with the greater feeding shown both with night time available food types and from night captured individuals. It was hypothesized that krill may break down their respiratory pigment, haemocyanin (Hc) possibly for nutrition during these periods of low feeding during the day. In a field experiment, day captured krill had significantly lower Hc concentrations ([Hcl) than individuals captured at night. There was a clear cost to the lower [Hc] of day caught krill as concentrations of lactic acid in the haemolymph (indicating an 02 debt) were significantly greater in these day captured krill than compared with night captured krill. Consequently it seems that krill break down Hc during the day probably for nutrition because, for whatever reason, they do not feed extensively on the food types available to them in the deeper depths they reside within during the day. As they ascend to the surface layers at night, where they feed to significantly greater levels on the available food types, they appeared to rebuild their [Hc] and recover from the 02 debt they incurred during the day. Feeding experiments examining the recovery of [Hc] with food types available during either the day or night showed that after starvation krill recovered their [Hc] significantly quicker (and possibly to higher levels) with night available food types compared with day available food types. As they appear to be opportunistic omnivores it is proposed that this feeding strategy would facilitate the recovery of their daytime incurred debts. Krill appeared to show an asynchronously DVIVI and in particular female krill appeared to ascend to the surface layers of the water column earlier than males. In fact female krill showed a more extreme pattern of metabolism during DVIVI, with significantly greater [Hc] (ca. twice that of males) but also greater lactate debts with the breakdown of their Hc during the day. The earlier ascent to the surface layers and also the much greater [Hc] of females may indicate that they have greater metabolic demands than males. The asynchronous pattern of krill DVIVI supports the hunger - satiation hypothesis for DVM. If satiation is modified to also include the recovery of daytime incurred debts the findings of this thesis do indeed fit this hypothesis. A tentative model is proposed for krill DVM where krill break down their Hc during the day and then recover at night with feeding in the surface layers of the water column.

Full text
Abstract:
Underyearling Bear Lake sculpin exhibit a diel pattern of vertical migration throughout the pelagic region of Bear Lake (Utah-Idaho) until they are approximately 22 mm standard length. Individuals move from the bottom of the lake (5° C) during the day into the water column (13-16° C) at night. The migration, however, is not related to feeding. Although the dominant copepod in the water column, Epischura nevadensis, do undergo a similar diel vertical migration, stomach analysis of juvenile sculpin captured by trawling shows that they do not feed in the water column. Instead, from July through October, their diet is dominated (70-93%) by benthic copepods and ostracods. Also, gut fullness of sculpin increases through the daylight period and decreases through the night, reaching minimum levels just before the dawn descent. Furthermore, feeding trials conducted in the laboratory show that juvenile sculpin feed most efficiently at light intensities found on the bottom (30-60m) of Bear Lake during the day. Feeding rate coefficients increase markedly from 1013 photons m-2S-1 until peaking at intermediate intensities of 1016 photons m-2S-1 and then decline at higher light levels. Although they do not migrate to feed, the movement into the warmer water appears to increase the sculpin's digestion rate, thereby allowing continued feeding during the day. This supports the hypothesis that diel vertical migration in Bear Lake sculpin is a thermoregulatory strategy that increases growth rate.

Abstract:
Diel vertical migrations (DVM) comprise the largest animal migration on the planet and are a phenomenon present in all bodies of water on Earth. A strong sound scattering layer undergoing DVM was observed in the Straits of Florida via a bottom-mounted Acoustic Doppler current profiler (ADCP) Workhorse Longranger 75 kHz (Teledyne RD Instruments) located at the 244 m isobath. ADCP average backscatter showed a clear periodicity corresponding with sunrise and sunset times indicating the presence of a nocturnal DVM. Analysis of the ADCP backscatter data indicated zooplankton swimming velocities were faster during sunrise than sunset times. In several cases the zooplankton swimming velocity appeared to be faster at the beginning of the descent, after which the swimming velocity decreased. Analysis of ADCP velocity data indicated a measureable decrease in the northward component of the current velocity field during migrations (sunrise and sunset) compared to three hours prior. This was presumably associated with an increase in drag due to turbulent friction associated with DVM. A non-hydrostatic computational fluid dynamics (CFD) model with injection of Lagrangian particles was utilized to simulate the effects of DVM on the velocity field and turbulence signature of the Florida Current. A domain simulating a section of the Florida Current was created and zooplankton were represented by particle injection with a discrete phase model. The model was run with and without particles, holding all other parameters the same, for comparison. Idealized temperature stratification and velocity profiles were set for both summer and winter conditions to observe seasonal differences. For each case, velocity and turbulence with particles were compared to results without particles to confirm the changes in profiles were due to the zooplankton (Lagrangian particles). In several cases there was an observable change in average x-velocity profiles due to the injection of particles into the domain. In all cases there was an observable increase in subgrid turbulent viscosity in the wake of the injected particles. This effect was much stronger in the winter case, most likely due to stratification of the water column which gave a near critical Richardson number. These results indicated that DVM does in fact have an effect on the velocity profile and turbulence signature in a strong current under certain conditions and that there was a seasonal difference due to stratification profiles.

Abstract:
Plankton are generally considered good indicators for ocean climate variability, but plankton data from the Arctic are still comparatively scarce. Due to this scarcity of information, the prevalence of vertical migration behaviour at high latitude is still debated. Atlantic inflow is a key process governing biological diversity in the Arctic Ocean, and the location of the Svalbard archipelago makes it an ideal study area to monitor this inflow. Comparing the zooplankton community within the fjords of Svalbard at various latitudes allowed us to assess the influence of Atlantic inflow and any subsequent changes in zooplankton composition that may have implications for higher trophic levels. Using sediment traps deployed on oceanic moorings, Chapter 3 of this thesis analysed long term observations from sea-ice dominated Rijpfjorden for the first time, and compared the zooplankton to Atlantic Water influenced Kongsfjorden. Chapters 4 and 5 investigated the spatial relevance of our moored observations using shipboard observations, and chapters 6 and 7 present observations of vertical migration across a range of conditions. Kongsfjorden was dominated by Calanus copepods associated with Arctic and Atlantic water, and strongly influenced by Atlantic Water advection. Rijpfjorden was largely influenced by sea-ice formation with higher proportional abundances of macrozooplankton species. Advection brought Atlantic associated species into Rijpfjorden during warmer years. Prevailing hydrology and bathymetry were highlighted as factors forcing zooplankton distribution, while advection was identified as responsible for much of the observed small scale spatial variation amongst weaker swimmers. At an aggregation scale of 0.5 nautical miles, zooplankton distribution was highly patchy and moored observations could only be reliably expanded outwards to a maximum of 1 nautical mile. Low amplitude diel vertical migration (especially by younger copepodids) was identified in surface waters when a food source was available. These observations must be considered within the dynamic framework of advection highlighted by this thesis.

Full text
Abstract:
The widespread occurrence of diel vertical migration behavior in pelagic aquatic organisms suggests that there is a selective advantage of the behavior compared to a static vertical depth distribution in the water column. Juvenile sockeye salmon (Oncorhynchus nerka) are active diel vertical migrators within pelagic lacustrine habitats, usually migrating over vertical distances covering tens of meters. The migrations are timed such that the animals occupy shallow depths during crepuscular and nocturnal periods, and spend daytime periods relatively deep in the water column. Hydroacoustic surveys were undertaken in fifteen British Columbia sockeye and kokanee lakes in order to compare predictions from selective advantage theories with the performance of the animals under field conditions. Juvenile sockeye undertook diel vertical migrations in all systems studied with the exception of Nimpkish Lake, where the migrations were periodically reversed, and Chilko Lake, where the migrations were periodically relaxed. None of the single factor theories correctly predicted all of the features of juvenile sockeye diel vertical migration. A multifactor theory, which interpreted the migration as a three-way compromise between foraging, predator avoidance, and the optimization of nocturnal metabolic efficiency, provided the most realistic explanation for the selective advantage of the behavior. The field observations also supported a hypothesized sensory mechanism for the behavior involving light and temperature controlling the day and night depth positions respectively. Two distinct kokanee diel migratory patterns were observed within Okanagan Lake. One group of animals migrated in a similar fashion as juvenile sockeye, while the second group undertook a reversed diel vertical migration. Target strength estimates from a high frequency echosounder suggested that small juveniles comprised the first group, while larger sub-adults comprised the second. The field observations are consistent with an ontogenetic shift in kokanee diel vertical migratory behavior within Okanagan Lake. Crustacean zooplankton prey organisms of juvenile sockeye maintained static diel vertical distributions within three Eraser River system sockeye lakes. Within Babine Lake, the cladoceran Bosmina coregoni undertook reversed diel vertical migrations probably in response to the vertical migrations undertaken by the predatory copepod Heterocope septentrionalis. Within Nimpkish Lake, where juvenile sockeye undertook reversed diel vertical migrations, B. coregoni as well as other planktonic Crustacea undertook diel vertical migrations. The correspondance between vertical migratory patterns in zooplankton and planktivores suggests a tight coupling in the diel migratory behavior of adjacent trophic levels with potentially important consequences for pelagic aquatic community structure.

Abstract:
Abstract Miniaturization of electronics modules is always required for various medical applications including wearable technology, such as hearing aids, and implantable devices. Many types of high-density packaging technologies, such as package-on-package, bare-die stack, flex folded package and Through Si Via (TSV) technologies, have been proposed and used to fulfill the request. Among them, embedded die technology is one of the promising technologies to realize miniaturization and high-density packaging. We have developed WABE™ (wafer and board level device embedded) technology for embedding dies into multilayer flexible printed circuit (FPC) boards. The WABE package is comprised of thin dies (85 μm thickness), multi-layer polyimide, adhesive films and conductive paste. The dies are sandwiched by polyimide films with Cu circuits (FPCs). The conductive paste provides electrical connections between the layers as well as the layer and embedded die. First, each FPC layer is fabricated individually, and via holes are filled with conductive paste, and the dies are mounted on certain layers. Then, all layers undergo a one-step co-lamination process, and they are pressed to cure the adhesive material and conductive paste at the same time. This WABE technology has enabled multiple dies to be embedded by the one-step lamination process. Even if multiple dies are embedded, the footprint of a package can be reduced drastically by embedding multiple dies vertically in stacks. This paper describes the details of the results of fabricating a test vehicle with six embedded dies (three-dies in two stacks side-by-side). The fabricated test vehicle had 14 copper layers with less than 0.9 mm thickness. This paper also reports the results of various reliability testing on the package. These results were obtained by electrical measurements of daisy chain patterns formed between some of the layers. The fabricated test vehicle showed high reliability based on the results of a moisture and heat test and heat-shock test. These results show that the WABE technology to embed multiple dies vertically in polyimide film is one of the most promising packaging technologies to significantly miniaturize electronic circuits such as medical electronics.

Abstract:
The convergence and miniaturization of the consumer electronic products such as cell phones and digital cameras has led to the vertical integration of packages i.e., 3-D packaging. Chip-stacking (3-D) is emerging as a powerful tool that satisfies such Integrated Circuit (IC) package requirements. 3-D technology looks to be the future of hand-held electronics; hence, making it an important research area. Stacked chips are peripherally interconnected through wires; this increases the package size and usually requires an extra “interposer” layer between the chips, causing substantial delays. Due to high package density and chip-stacking on top of each other, heat dissipation from the die becomes a concern. To overcome these thermal challenges and provide better inter-chip and chip-substrate electrical connection, Through Silicon Via (TSV) technology is being implemented in 3-D electronics. Electrical interconnection and heat dissipation improves with the number of TSVs. But, there is a trade-off; TSVs occupy the chip real estate, resulting in reduced silicon efficiency when compared to the baseline (no-TSV) scenario. Coefficient of thermal expansion (CTE) mismatch and reduced chip area causes thermal stresses and may lead to premature chip failures. This can be a major reliability issue. In this paper, a parametric study of the number of TSVs in a test vehicle (TV) consisting of 2 vertically stacked dies and TSVs (between the die and the substrate) has been performed using ANSYS WORKBENCH. A quarter symmetry model has been formulated to study the various cases as a function of number of TSVs. Each die has an area of 5.7mm2 with 0.1-mm thickness and 0.5W power rating. The TSV diameter is 50-μm each with a SiO2 insulation film of 25-μm thickness. Junction temperature and thermal resistance is determined to obtain the best case in terms of temperature distribution on the die. Furthermore, thermo-mechanical analysis is performed for all the TSV configurations and a guideline is proposed based on thermal and structural response.

Abstract:
This paper describes design, fabrication and preliminary characterization of a proof-of-concept vertical-travel microactuator, providing linear motion and high precision positioning in space. The microactuator is capable of providing latching function when it is un-powered to maintain its position. The microactuator consists of two opposing comb drive actuator dies, a slider and bulk PZT actuators sandwiched between the dies. The slider is inserted between clutches. Comb drives are connected to the clutches to engage/disengage clutching. Sequential activation of the comb drives (in-plane motion) and the PZT actuator (out-of-plane motion) provides cumulative linear travel of the slider. The novelty of the slider insertion approach include (1) post-fabrication engagement of comb teeth enabling thick wafer DRIE process for comb drive actuators and (2) stressed tethers enabling zero-power latching. A test device was fabricated and assembled. By applying 100V∼300V DC to the electrostatic comb drive, lateral actuation of clutches was observed. Vertical actuation by PZT was also confirmed using WYKO RST plus interferometer.
